Welding tool



Patented June 14, R927@ UNITED STATiS PATENT OFFICE.

Application filed Saly 7. P5225. fier-tal No. e.

This invention relates to welding toois for use in connection with electric arc welding, and contemplates, more particularly, the production oi' a safe, efficient, and durable tool in which` the possibility of shock and excessive heating is reduced to a minimum. and the rapidity of conducting electric current to the electrode is materially increased.

The main object of the present invention is the provision of a Welding: device for gripping and holldine; an electrode, said, device including a handle grip of heat and electrivcal insulating; material attached to the current conducting; member by means connecting the .said handle grip from the under or inside thereof, said means terminating short of the exterior or outer faces of said grip.I about which the hand of the operator positioned, thereby preventing the porsibi-lity of shock.

Another object of the present invention is to provide a welding device including a tool formed of copper for conducting the electrical current. and holdingr the electrode a hand grip of heat and electrical insulating material for said tool, and means for detachably connecting an electric conductor to said tool.

A further object of this invention is to provide resilient means for normally holdingr the electrode gripping jaws firmly .in contact with the electrode, but still provide an easier operating tool `and one in which greater leverage is obtained With less efforton the part of an operator thereof.

`With the above and other ol'ijects in View, the invention further consists in the construction and arrangement of the several parts hereinafter described and pointed out in the claims.

n the drawings` in which similar characters of reference designate similar parts in the several views:

Figure 1 is a vertical sectional 'View of tbc tool of the present invention` and Fig. 2 is aview ot' the Welding tool in side elevation, showing also, the ends of the conductors attached thereto.

Referring now, more particularly xto the drawings., the Welding tool of the present invention includes 4a handle portion provided With a heat and electrical insulating grip, an electrode holding device at one end thereof, and means for easily and rapidly attaching` an electrical conductor to the other end of the tool.

ll`he tool of the present invention is in the form or a pair of tongs consisting of two current conducting members l-1, pivotally connected tog/'ether'by the pin 2. The' current condueting'inembens are of relatively 'tough and durable metal capable of Withstanflinp; the Welding beat and are also good conductors of the electric` current, said membersb-eing formed preferably of copper and offering' little resistance to the tion' of the current therethrough.

Euch current conducting member comprises a jaw portion, the gripping face of 'which is smooth and unmutilated as indi cated at. 5and a shank portion 6 providedl scribed has been found to materially increase the effectiveness of the tool, the long delays incident to the breaking of ermanently at tacbed conductors being obviated.

The current conducting members of the tool are each provided with a hand grip 13, said grip being formed of a heat and electrical insulating material. As shown, the band grips 13 substantially surround the current conducting members 1. that is, the

portions of said members 1 which would be exposed to possible Contact during the use ot the tool.- The interior faces of the grips lf3 contact With the outer face of the current conducting members 1 as shown at, 14:.- f desired, an air space( brmed between the inner face or" the hand grip and a longitudinal flattened portion of the current conduct,- ing members 'l may be providedi this air s ace beingr located intermediate thev hand grip 13 and the current conducting member and at points principally covered by the hand o the operator when grasping the tool. The air space may be relatively large and located longitudinally and centrally ci
